All you need to know about our conservatory replacement roof system

Our replacement roof systems can be added to almost any conservatory. They are lightweight, long lastly and extremely thermally efficient. So how do we manage to do all that?

Special lightweight rafters

We start by removing yoru existing conservatory roof, and then rebuild it.  Conservatories used to be built from wood, aluminium or uPVC but we use the latest ‘Glass Reinforced Plastic’ (GRP) rafters to create a completely new roof frame. These GRP rafters are lightweight and improve the structural integrity of your conservatory.  Unlike other materials like wood or Aluminium, GRP is not prone to:

  • wood worm
  • moisture absorption
  • condensation
  • thermal bridging  

The first layer of internal sheets

Special internal sheets are then added underneath the GRP rafters. These are 100% waterproof and again, they are very lightweight. They are also thermally efficient, adding to the overall efficiency of the roof. 

Insulation sheets

We use an all in one insulation solution that also acts as a vapour barrier and roof membrane. It’s ultra-thin, multi-reflective and has 4 layers of aluminium insulation materials which are thermally welded across all its surfaces.

This provides improved sound insulation and makes the insulation up to 13% more effective than 200 mm of mineral wool. It is also as durable as aluminium, resistant to shrinkage and rot, and fire resistant.

The outer layer

Next, strong, load bearing and insulated outer sheets are added. These ensure less roofing bars are needed and again, they are thermally efficient.

The outer boards are:

  • A structural alternative to plywood
  • A significantly lighter alternative to any other roof covering board
  • A 100% waterproof outer covering

High quality Tapco tile finish

TapcoSlate tiles are lightweight and create a classic finish. Indistinguishable from natural slate, the tiles we use don’t crack, break or delaminate, and are durable and longstanding. They weigh as little as 12kg per square metre and are quick to install with pre-marked nailing and exposure guides and spacers. They come in a choice of colours, have a 40-year warranty and have been fully tested to BBA, ETA and CE standards, including for fire rating, wind, driven snow & rain, and water absorption.

Internal finish of your choice

The internal sheets we use do allow for a traditional plaster skim finish if that’s your preference, or we can use standard 12.5mm plasterboards.

All the materials we use have been chosen because they are high performance, long lasting and cost effective. Brought together as part of our conservatory roof replacement system, they create an outstanding roof which looks stylish and elegant and will last for years! Why not get in touch to find out more?

And if you’re having trouble with cracked, broken or damaged glass in your conservatory, it may be that you have too.
